The Bridgestone Picnica is a belt-driven bicycle introduced in the early 1980s and carried in the Bridgestone Cycle USA catalogs from 1985 through 1990.[1][2] It weighs 29 pounds and uses a tooth-belt drive like auto timing belts and Harley-Davidson drive belts, along with a novel two-part chainring that increases belt tension with increasing load. The Picnica is a folding bicycle, and part of the appeal of the belt drive is cleanliness. It is a small wheel bicycle, so belt tension may be less than on a bicycle with standard-size wheels.

The Picnica was apparently commercially successful, but was offered mainly in Japan.
